Trivia: Such was the popularity of Doctor Who in Britain in the mid-1960s that even the Beatles wanted to make an appearance in the show. So a scene was written into "The Chase" to allow them to appear. The idea had been devised of including a scene on the Time and Space Visualiser depicting a Beatles fiftieth-anniversary concert in 2015, with the Fab Four dressed up as old men. John, Paul, George, and Ringo themselves were interested in the proposition, but it was vetoed by their manager, Brian Epstein. It was then thought that an appearance by the Beatles on Top of the Pops might be used instead, but no such footage was available. Fortunately, the Beatles were scheduled to perform "Ticket to Ride" at Riverside Studios in Hammersmith on April 10th, 1965, and that footage was used instead.
The Forms of Things Unknown - S1-E32
Trivia: This is the only Outer Limits episode that lacks both opening and closing narration. It was absent because "Forms" was the unsold pilot for a series called The Unknown. A second version, stripped of all its supernatural elements (Tone was simply a mad scientist, not a real time traveler), also failed to sell.
Trivia: Here and in several other episodes, Burke's Law was one of the first TV series to break with longstanding Hollywood prejudices by hiring Latino actors like Cesar Romero to play Latino roles. In this episode, three years before becoming the Joker on Batman, Romero plays a Mexican police chief interrogating Amos Burke, whose rather prescient line to him is, "The joke's on the joker - I've been framed!"

Trivia: This was the first US TV series ever to resolve its story line and air a definitive ending, despite network objections that doing so could harm its syndication revenue. The 2-hour finale, "The Judgment," garnered the highest TV ratings ever up to that time, a record it held for many years afterward.
